(Cl.l Sli-34T 'Ihis invention relates toimprovements infdryshaverclipper attachments.

A1 certain type of'dry shaver orelectric razor is provided With aclipperrattachment,y the purpose 'of'Y which is tov shear or cut' (notasclosely as in shaving) hair which is too longto enter'the rela tivelyshort interior slots of :the regular shaving heads-of4 the razor,or-which would be missed'by the latter, wherebythe remaining'stubble maythereafter be properly shaved when passed over by theconventionalshavingl head of the electric razor; The'conventional:clipper attachment reierred to comprises=a laterallyprojectingY comb mounted' exteriorl'y and' longitudinallyA of thesiottedbarrel of a' dry shaver head,y and a cooperatingreciprocalclipper- The latter is connect'ed by'an offset' arm withthesamerocking shaft used'tol drive the main cutter; to be reciprocatedthereby relative to the'stationary'comb member and is engagedl by aresilient member extendingV angularly' from saidI arm.v This arrangement Was-found-to lie-'objectionable -in that when the razor withits-clipperattachment was used a rocking motion'rwas imparted tothereciprocal clipper which permitted the -clipper or 'blade to tilt awayfrom the comb; retarding effectivev operation thereof;

With the above inv mind, itis ak primaryobject ofv the present inventionto provdea dryshaver; clipper; attachment wherein the clipper"attachment' is yassociated with the sh'aver'head in an extremely simpleand effective manner such as Will insure proper operation of theclipper' or blade relative to the stationary comb'fwithout' danger ofdeflection of' said' blade i avvayffromA the plane of the comb;

A furtherA object of theinventionis to provide a dry shaver clipperattachment-wherein themow able clipperl elementv isv operatively mountedon and engaged 'with the' reciprocal jshavingcylinder and is resilientlysupported laterally: of" the cyl inder and in proximityv tothe-clipper-comb by' adequate members exerting forces at right angles tothe planefof the vclipper and in amanner so that themovableclipperelement wil1` nott bev rocked or'deilected'awayfrom the combduring use;

A further` object ofthe invention is toprovidevv thatit`is-actuatedibyfmeans alliinv theiplane' offorms of dryshavers withlittle modification of thelatter,` ay dry shaver with the attachmentbeingsusceptibletof easy andfconvenient assemy bly-and disassembly;andifacilitating repairs and replacements:

Byway'of illustration the head end of a dry shaver orelectric razor,with which the improved clipper attachmentI is associated, is shown inFigs. l. to Il-inclusive of thedrawing and is designated generally bythe numeral 8;' Said razor includes a hollow handle or body 9 in whichis housed a smallrelectriemotor (notshovvn) and the latter reciprocatesor vibrates an upwardly projecting arm= I0'.

Removably mountedion .the recessed outer end ofthehandleor-body- 9-isfthe dry shaver head whichzisfretained: in theimounted position vshownby a set screw I2 which extends through the handle and impinges againsta base portion I3 of the shaver head, the screw also being used in thepresent invention for clampingly engaging the angularly connectedsupporting wall I4 of a clipper attachment comb I5, as will hereinafterappear.

The head of the dry shaver or electric razor includes a hollow outershell I 6 whose projecting portion is substantially semi-circular incross section and provided With depending walls which are secured to thebase portion I3, as best shown in Fig. 3. The senil-circular curvedportion of the shell I6 is provided with series of hair receivingopenings I 'I with bars thereadjacent. Adapted to cooperate with thecurved projecting portion of the shell I6 is an inner cutting cylinderI8. The latter is arranged to fit snugly against the inner curved wallportions of the shell I6 and to be reciprocated axially thereof. Forthis purpose a lower wall portion of the cylinder member S8 is providedwith an aperture which is entered by the reduced outer end of theprojecting arm Il which, through its connections with the electricmotor, is vibrated or reciprocated and in turn imparts these motions tothe cylindrical member i8. The upper wall of the cylindrical member I 8is provided with series of cutting bars IB which, during the operationof the razor, reciprocate axially relative to the stationary shell I6moving relative to the slots I'I and shaving hair which enters saidslots by virtue of the shearing action as between the edges of the barsI9 and I'I.

The improved clipper attachment `is associated.

with the head of the electric razor and includes the angularly shapedcomb I previously mentioned, and a reciprocal clipper element or bladeshown in detail in Fig. 6. The comb I5 is rigidly mounted in theposition shown in Fig. 3 with its wall I4 abutting the outer face of aninwardly extending side of the shell I6 and having its extended portionreceived within a body slot 2l and clampingly and removably engaged bythe set screw I2, previously mentioned.' The comb also has an integral,laterally projecting serrated comb ledge 22. The opposite ends of theouter portions of the comb wall I4 are provided with slots 23.

The reciprocal blade 2D is an elongated ilat element having its outerlongitudinal edge serrated and having inturned hooked extremities 24spaced from the other edge. The blade 2D is adapted to underlie the combledge 22 and when the device is assembled and in operation the blade isreciprocated relative to the stationary comb ledge and the movement ofthe blade serrations relative to the ledge serrations is effective tocoarsely shave hair entering the combv ledge and blade slots. The endslots 23 in the comb wall I4 receive the transverse ends 25 of the bladewith sucient play to permit longitudinal movement of the blade. It willalso be observed that the end portions of the adjacent wall of the shellI5 are slotted as at 26, in registration with the comb wall slots 23 andaccommodating the transverse ends 25 of the blade. Said transverse ends.25 of the blade also abut against the ends of the inner cylinder I8 ofthe shaver with the hooked extremities 24 of the blade extending intothe cylinder. From the foregoing it will be obvious that the clipperblade is attached to the reciprocal cylinder I8 of the shaver and hence,reciprocations of the cylinder are imparted to the blade. ""he blade, aswill be seen from Fig. 3 extends laterally of the shaver shell and itsplane substantially includes the axis of the reciprocal cylinder.

The arrangement described permits of very easy assembly and disassemblyof the clipper attachment and blade relative to the shaver head. Themounting of the clipper comb was previously described as was therelationship of the blade to the comb and elements of the shaver head.For assembly, for instance, if the cylinder I8 be disengaged from themotor arm l0 then the cylinder can be manually turned through an angleof ninety degrees to bring a cylinder end slot from the position shownto one wherein a hooked end 24 of the blade may be passed thereintofollowing which the other hooked end of the blade may be registered withthe corresponding end of the cylinder. Thereupon the cylinder ismanually turned back to its original position and the hooked ends of theblade are closely and securely engaged with the ends of the cylinder,and the cylinder may be reengaged with the arm I0.

For proper operation of the clipper blade relative to the clipper combthe former should be se curely supported against deflection or angularmovement. The direct driving engagement of the shaver cylinder with theblade is very effective and in addition the underside of the blade isresiliently engaged by the outer ends of supporting pins 28. These pinsare spacedly mounted at right angles to the plane of the blade 20 andextend into recesses therefor in the shaver handle S. Thepins areoutwardly urged against the blade by confined, coiled springs 29.

In shaving, long hairs do not always readily enter the interior slots ofthe shaving head of the electric razor. The purpose of a razor clipperattachment is to permit shaving or cutting of such missed hair to renderthe same stubble which will thereafter be eiectively shaved by theregular shaving head of the electric razor, and yfor other conventionalclipping operations. A clipper attachment loses its eiectiveness,however, if the clipper blade can rock or move away from the comb duringoperation. In the present improvements this undesirable contingency iseffectively guarded against through the direct connection of the clipperblade with the shaver cylinder and the additional supports for theblade. As a re sult the clipper blade can not be rocked cr separatedfrom its comb and the mounting, support and drive of the clipper andblade is effective and simple.

, The dry shaver clipper attachment is easy and inexpensive tomanufacture and install, is strong and durable, and enhances the utilityof the razor.
